Beef Lung Cubes are made from pieces of beef lung, puffed up using hot air into a soft, chewy treat and cut into cubes for your dog. This method of preparation retains all of the nutrients found within the raw lung, whilst the soft texture and low fat status makes it a great choice for puppies and elderly dogs. These treats are a rich source of protein, vitamins and minerals, and their crunchy texture makes them a healthy and flavourful dental snack.
